Is God Three or One? Understanding the Fullness of Jesus Christ

Most of us grew up hearing the word “Trinity.” It’s everywhere — Sunday school, creeds, church bulletins. But when you actually sit with the Bible, something stands out: “Hear, O Israel: The Lord our God is one Lord” (Deuteronomy 6:4). That statement — the Shema — isn’t a theological footnote. It’s the bedrock of how God chose to reveal Himself.

The Mystery of the Incarnation

In the New Testament, that same one God stepped into history as a man. Jesus wasn’t a second member of some divine committee. He was, as Paul put it, “the image of the invisible God” (Colossians 1:15). The Creator didn’t send a representative — He came Himself.

The Fullness of the Godhead

The Bible doesn’t leave us guessing about who Jesus is. A few passages make it unmistakably clear:

Isaiah’s prophecy named the coming child “The Mighty God” and “The Everlasting Father” (Isaiah 9:6) — centuries before Bethlehem.
Jesus’ own words settled the question directly: “I and my Father are one” (John 10:30). Not one in purpose. One.
Paul’s summary to the Colossians is about as plain as it gets: “in him dwelleth all the fulness of the Godhead bodily” (Colossians 2:9). There’s no part of God that exists outside of Jesus.

Why the Name Matters

This changes how you read the Great Commission. When Jesus told His disciples to baptize in the “name” — singular — of the Father, Son, and Holy Ghost, the Apostles knew exactly what that name was. Every baptism in Acts was done in the name of Jesus. Not as a correction to the command, but as the fulfillment of it. They understood that the Father was revealed in the Son, and that the Spirit is simply the presence of Jesus with us now.

A Deeper Relationship

When God is truly One, He stops feeling like a theological puzzle and starts feeling like a Person. He’s not a distant committee. He’s the Father who loved us, the Son who redeemed us, and the Spirit who fills us — all of it wrapped up in Jesus Christ. When you call on that name, you’re not calling on a concept. You’re calling on the Almighty.
